DocuSign Add One Document to a Draft Envelope

See more DocuSign Examples

Demonstrates how to add one document to a DocuSign draft envelope. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Load a previously obtained OAuth2 access token.

// Adds the "Authorization: Bearer eyJ0eXAi.....UE8Kl_V8KroQ" header.

// Send the following request.
// Make sure to use your own account ID (obtained from Get Docusign User Account Information)
